# Inventory Record Analysis for Driveshaft Subassembly## OverviewThis section analyzes the partially completed inventory record for a driveshaft subassembly. The table provided details the gross requirements, scheduled receipts, lead time, and current on-hand inventory. It helps in understanding materials requirement planning (MRP) for manufacturing processes.## InstructionsComplete the last three rows (Projected on-hand inventory, Planned receipts, and Planned order releases) for a Fixed Order Quantity (FOQ) of 55 units. Enter your responses as integers, where '0' indicates that the particular action is not applicable.### Item: Driveshaft Subassembly#### Input Parameters:- **Lot Size**: FOQ = 55 units- **Lead Time**: 3 weeks### TableThe table is structured across a span of 8 weeks to record the inventory data accurately.| Week | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 ||------|---|---|---|---|---|---|---|---|| **Gross requirements** | 30 | 20 | 20 | 20 | 45 | 45 | 50 | 50 || **Scheduled receipts** | 70 | - | - | - | - | - | - | - || **Projected on-hand inventory** | 10 | - | - | - | - | - | - | - || **Planned receipts** | - | - | - | - | - | - | - | - || **Planned order releases** | - | - | - | - | - | - | - | - |### Explanation**Gross requirements** list the total demand for the driveshaft subassemblies each week. **Scheduled receipts** indicate any existing orders expected to be added to the inventory during that specific week.**Projected on-hand inventory** tracks the expected inventory remaining at the end of each week after accounting for the gross requirements.**Planned receipts** are the quantities expected to be delivered based on the planned order releases.**Planned order releases** are the quantities to be ordered to meet future gross requirements considering the lot size and lead time.### Objectives1. Keep the projected on-hand inventory from going negative by planning orders.2. Determine the correct timing and quantities to place orders to ensure there are sufficient materials for production.To accomplish this, consider the FO

The president of Hill Enterprises, Terri Hill, projects the firm's aggregate demand requirements over the next 8 months as follows: 2,200 January 1,400 May February 1,600 June 2,200 March April 1,800 1,800 July August 1,800 1,400 Her operations manager is considering a new plan, which begins in January with 200 units of inventory on hand. Stockout cost of lost sales is $100 per unit. Inventory holding cost is $25 per unit per month. Ignore any idle-time costs. The plan is called plan C. Plan C: Keep a stable workforce by maintaining a constant production rate equal to the average gross requirements excluding initial inventory and allow varying inventory levels.
